You can get good spin coaters for about $5-10k. I've seen them on ebay for lower. If that is not low enough, you can always build one with a simple DC motor. The tricky part is to get a vacuum line through the motor shaft. But if you are not going to do high rpms, you may not even need a vacuum hold.
