Hey Rainbow,
I have this bass (4-string model) and for the money it is hard to beat. I had gone to a 6-string Ibanez after years of playing 4-strings because there was something about most 4-string basses that caused my left (fretting) hand to cramp up a lot of the time (at the wrist.) I sold the 6-string after deciding to take a break from bass for a bit, but when I got the bug again, I went into a music shop, picked up an ATK200, and after playing for about 5 minutes knew that I wanted it...again, this was after YEARS of having trouble with most 4-string basses (including Rickenbacker...not saying Ricks are bad basses, just not for me.)
I have had the ATK200 for about 18 months and it is still fun to play. My only complaint is that I had a hard time closing the battery compartment cover properly, so much so that it eventually broke, but that is pretty minor.
Bottom line, a neat little bass for what you're going to spend on it. Highly recommended...

- Having said that, just because it works for me doesn't mean it's the bass for you. Try to get your hands on one and play it for at least 15 to 20 minutes, plug in to an amp if one is available, etc. Good luck...
