I'm using one as my main rig, I think it's a great piece of kit, and will certainly give you lots of options for home practice & home recording. The Bass Model pack is essential, and also very good.
Good headphones are a good investment, either good quality Hi-Fi, or Pro Music headphones, I'm using a pair of Sennheiser HD200's and they're pretty good, I also plug it into my home stereo. For band use, I plug it into the rehearsal room's amp setup, using the Power Amp In or Effect Return, bypassing the amp's pre-amp.
I got mine second hand, and you can get a nearly new, well looked after example with the original boxes for £250-300. Money well spent IMO.
