I've played a few Ibanez basses (although not the exact model you're asking about), and they were good, but if you can snag a US Mill for that price, DO IT! RUN, don't walk, and snatch that thing up. Worst case scenario, you don't like it and you can flip it. US Mills are amazing instruments in every way possible... fit and finish is great, they feel and play wonderfully, and they sound amazing. I've read elsewhere that they were meant to be competition for US Laklands, if that gives you an idea of what you're in for. DO IT.
