Get whatever moves you because if you're new to bass, chances are you won't be sticking with whatever bass you choose forever or for all that long necessarily. Especially if you hang out here for any significant amount of time.
Welcome to here.
This 100%. If your local L&M does not have what you want go play what they do have. Drive to any music store you can and try basses. Your only goal should be how it feels. It is much easier to learn on a comfortable. Instrument. Be assured that you can find something nice within your budget. ESP, Squier, Yamaha, Sire, SUB, Peavey and apologies to any left out .Yamaha is a great company to go with as well, you should be able to find something in the same price range as that LTD you are looking at (Yamaha makes everything from $300 instruments up to $2500 - $3000.) But like a lot of others who have posted here, I would strongly suggest that you consider going used for your first bass. For every person who stuck with learning/playing their instrument, there are ten who gave it up pretty quick...if you fall into the latter group, then you won't have spent as much money...
P.S. Where do you live? You say there is a Long & McQuade somewhere nearby? Any other music shops? If you are dead set on buying new, you should try a few different shops if there are any around and do a bit of comparison shopping.
P.S.2. Playability should be the most important aspect of whichever bass you choose to go with, ESPECIALLY as a beginner. You may like the looks of that LTD, but even if it has a decent setup, if the neck shape/radius and/or scale length aren't comfortable for you, you may end up with cramping issues, if not something more serious like tendonitis. I owned a Rickenbacker bass that I sold in 2010 when I finally admitted that it wasn't - and never had been - for me. That was a bass that I bought largely because some of my heroes played it and also, yes, because I liked the looks of it, but it caused me nothing but issues. I know that as a beginner you may be a little reticent about going into music stores to try out several different basses, but it really is the best (and only?) way for you to get a feel for what will work for you.
Feel first, then worry about an amp.
