Well, in reality, you're getting what you pay for. Arii (ex-Otaki) kits are a good bang for the buck.
I've built their Spitfire VIII and Fw 190A. These two kits fit fairly well and have decent detail overall, but lack a bit in areas such as the cockpit. Also, the glass is sometimes not so clear, and none of their kits come with the option of opening the canopies.
Other Arii/Otaki kits don't look as nice in the box as the 190 & Spit, but most are okay. I did build the P-40, Ki-44 and Ki-84 when I was just starting out, but I couldn't tell you much about them. Memories of a ten year old aren't reliable, especially after 20 years! LOL
If you're looking to get something like a Tamiya kit... buy a Tamiya kit.
But if you just want something quick to build, or perhaps a testbed or two to try new techniques out on, these would be perfect.
