Let me first assume you are not trying to promote your keyboard products.
$50 is not a good place to start when you want "the best keyboard", but a decent one can be acquired new from the $100-$150 range (junk yard finds and garage sales are some other stories).
I will recommend Cherry MX linear switches, possibly red or black, and the newer (retooled) versions, for the sake that these switches can be backlit easily, with the primary support from PCB suppliers, and are very compatible with key cap sets out there. There are some decent Chinese clones, arguably comparable to Cherry's offers, but if you are going to have only 1 board, then go with Cherry.
At least when people pull a cap, they may believe "you know something" when they see Cherry - of course this is again controversial here.
This is the time I will recommend discount shops like KBDfans.cn (Google it and you will find their shop) - they will easily solve your case, PCB, and key cap set problems. Any option other than the basic case (tray-mount) regardless of the layout and the keyboard size will make your board x2 and x3 or even more times the price range of $100-$150.
It's not going to be "the best" - at least for quite some people out there in the mechanical keyboard forums.
But I believe you will probably like it.
If after a few more months you return and show a $500+ built truly worthy of praise with the choice and careful preps of parts, or that you return and show a legendary keyboard relic unearthed by you,
then the virtual community will genuinely endorse you.
