Ship display case

Ok, I'm working on the 1/350 Tamiya Yamato and I'm needing a display case for it. I'm not looking for a mirrored background or anything like that. Just a nice arcylic cover with a sturdy base, it can be either wood or heavy plastic. I plan to drill through it and use pedestals and mount the ship on them. The measurements for the case would be roughly L=30 in., W=7 in., H=8 in. Does anyone have a good source for these that aren't too expensive.......Most of the ones I've seen are >$150...... :-S

I think if you want quality you will burning cash for sure.
