my unpopular opinion here is that i dont like any keyboard that oesn't have standart mx style switches.
MX's proliferation can objectively be attributed to only two things: long-term reliability (for the cost and size), and a significant historical market share of the industrial and POS markets that weathered the rubber dome apocalypse while its competitors either folded or left the market space.
MX is not the standard today for any other significant reason. If those are the only reasons that we, as enthusiasts, settle for MX ... then the standard needs to change. I don't think you'll find a majority of people who would try something like Alps (in good shape) and go right back to their MX browns, etc, if not for their compulsive obsession to customize everything. The very fact that that is the case is also the only reason that it remains so.
topre-rubber basically a membrane that activates mid travel aalso expensive
There are some very good dome-with-slider boards that come very close to Topre. I'm told there are even some good modern "memchanical" boards. Topre and Niz boards are worth the cost though if you like tactile switches. Try them.
alps- heard they have good clickies but they dont work for standard pcbs now and are hard to get and im talking about original ones
In addition to what CaesarAZealad has already deftly said, and what I have addressed above, look into Zeal's new Clickiez switches. I have them in one board and ordered a few hundred more based on my impressions. I like them more than Kaihua's box switches and those were the only MX compatibles I could stand anymore previously. They can compete with Alps (to my preference). They are extremely stiff in the tactile configuration though. Maybe they'll make something more ... normal down the road for the tactile fans.
buckling spring- heard that original ibm keyboards are pretty expensive also old and only clicky not removable too
Unless somebody doesn't know what they have, have too many of them, or wants to spark a fire in someone new, the Models F are expensive ... yes. Standard Model Ms haven't really changed significantly in value in years and Unicomp still makes their own variants to this day for a reasonable price. I don't like membrane buckling spring at all anyway, but to each their own. Capacitive buckling spring is worth the price, and Ellipse should still be selling reproduction 4704 IBM boards ... they are worth every penny.
other strange old switches -no
Why not? The weird/obscure ones are the ones you're most likely to get for a reasonable price. NEC blue ovals are fantastic clicky switches, and you're more likely to find a good dome with slider board than a bad one. I would take any of those over anything MX myself.
