What is your dream rig? You seem to already know. Personally I would not buy your "pro rig" now, as by the time you get good enough to make use of it you might want something else. I played for almost a decade before I got into heads and cabs and when I did I bought a used rig with the plans to change parts once I got more bread. Buying used allowed me to not lose any money, if I did it was negligible/cheaper than renting. If money is absolutely no issue, then do what you want with it, but for me personally I felt I had to earn better gear. I get a laugh when ****** players show up to gigs with professional gear, I know that one day I can buy their expensive stuff for cheap when they stop playing. I personally will avoid an amp with built in stuff, in my mind adding extras is to make up for something it lacks. Plus I come from a small town, business usually don't do one thing well, they do several things poorly, that gets old. I prefer my pedals/amps/everything to do one thing well. That is it. If I was in your shoes OP I would look at the Roland MicroCube. Great tone, small package, built in useful features. I love mine, but it is expensive for a practice amp, around $300 after taxes. The modelling in it is pretty decent but the built in tuner and drum machine/metronome are worth the price of admission. It is also the standard amp for buskers in my experience as you can battery power the amp if you choose.
