Here's my sad little story:
Around 1983 I did a bunch of research on the "best bass amp." I ended up special ordering an Ampeg SVT and 810. When it come in, the store called and said come try it out. It sounded nothing like I imagined. In fact I thought it was so awful that I wondered if it was broken, or possibly a black market fake. Since it was special ordered, I paid it off and made do. Over the years I have occasionally come across SVT with 810s in stores. They all sound pretty much the same. It's just not my sound
The gas powered yard equipment that did not work out for me is a walk behind string trimmer. The areas where I need to use it have too steep of an incline.
Regarding progressives. I am pretty severely nearsighted and I am on my second set. My opinion is mixed...they are better in some ways and worse in others. I buy dedicated single vision readers, as I can't read for long with the progressives. I also feel progressives suck for sharp peripheral vision, which I found a bit concerning for driving. To overcome this I turn my head more at stops.
Getting used to a new progressive prescription seems to take much longer than single vision. The first prescription took almost a year. I adapted to the second set much quicker; maybe 3-6 months. The main issue for me was getting used to the distortion in my field of vision as I am looking around. The distortion creates a sensation sort of like vertigo. After fully adapting to a prescription, I stop noticing the distortion.
I do feel progressives allow a wider range of reasonably sharp vision. So after my brain learns to compensate, progressives give a more natural experience in the mid to far vision range. I suspect they would not be ideal for activities such as tennis of soft ball.
Regarding two-stroke power or gas VS electric power.
I love my gas power and usually have no problem getting it started and keeping it running until it gets old/worn out. Last year my Ryobi blower and weed eater crapped out after almost 20 years of service. I also have a Craftsman mower that bought about the same time. The pull chord on the blower broke. I was going to fix it, but when I pulled it apart I found some screws had come loose a stripped out. I bought a brand new top of the line Stihl. I miss the old Ryobi, but the Stihl is a step up.
The drive shaft on the weed eater locked up. I bought a used block off Ebay (because new parts are not available). I cannibalized parts from my old unit to make a complete power head. A few years back I bought a backup Toro powerhead that works with the same attachments.
Over the years I had to replace the fuel lines, primer bulbs and gas caps a few times. Also replaced a bump head and flex shaft on the weed eater, and fiddled with the carburetor jets from time to time. Both units were still running the original spark plugs. I don't bother running them out of gas as I start them regularly. I buy non-ethanol fuel and add Star Tron fuel treatment for all of my small engines (including motorcycles).
I have Stihl chain saw that I don't use very often. When I need it I fill it up with gas and it usually starts after a few pulls. When I am done with it, I drain the gas and run the motor till it quits. The chain oiler leaks while the unit is stored, but AFAIK that's pretty typical.
I also have about a 20 year old gas wood chipper. I usually wind up chipping two or three times a year to clear piles. When a big branch falls or a tree dies, I chip what I can and usually the rest gets put in my trash can a few pieces at a time. My chipper is rated to 3".
