Given that it's an early rev 4, I think you paid too much. That revision is difficult to expand due to different logic in the CPU and video slots. Some accelerators won't work at all, others will require you to pop the 68000 off the motherboard. It also lacks a Buster chip. which might give you some Zorro problems. If you upgrade the Kickstart past 1.3, you'll also probably have to do the old 1->31 pin swap trick (details are all over the place, Aminet probably has them too).
Still, it looks like you got a lot of bonus goodies with it too. Ultimately, if you're satisfied with it, it was a good buy.
