If you got the money, go ahead and get the ebay reds - honestly, I'm not aware of cheaper reds and you have the review of those who have already done so, to feel more confident about it.
If money isn't an issue, and you want the quiet, build quality and greater spill resistence - get the Topre. I'm gonna recommend a consistently weighted board, over variable for gaming, though, which creates some additional cost, obtainment issues.
Here's an important question: Do you need/want a low force key?
If the answer to the above question is YES, then ok, you should get reds, topre or homebrew reds.
If the answer to the above question is I don't know or no, then I recommend you do the following:
Buy a keyboard with cherry blacks - PCB mounted, so it will be easier to swap springs if you don't like them. There are more price options and keyboard feature options going this route. If you like the blacks, then you're done, problem solved. If the blacks turn out to be too fatiguing, then you're halfway to home made reds. All you have left to do is get the cheapest source of cherry browns and swap the springs.
Tenkeyless reds or blackstem + brown springs, would be my gaming board of choice. Someday I'll probably homebrew the hard\expensive way (Deck 82 and much, solder).
