Don't buy new full switch, buy or trade for used stem/spring only. Many people sell such after parting out 'junk' G80s, mods and so on, often can find packs of 87-105 around $20-30 depend on type how easy to find, clears usually harder as many people want them.
If you do go for new switch, I suggest only get enough for the primary typing block (62) as it give a good impression of the switch for use while saving some money.
