If you're not looking to use it to practice with others then it's not strictly necessary to have a decent sounding one, although I concede that it makes the whole practising experience a lot nicer. I've moved pretty much exclusively to practising through headphones these days, but I occasionally get my little (but very heavy) Trace Elliot combo out to annoy the neighbours. Honestly, any of the other major manufacturers (Ampeg, Ashdown, Hartke, GK, etc.) will give you something different to play with, so if you can get to a reasonably large shop you could take three or four in and try them out.
