Obviously price would vary by condition. My ideal board would be a leopold in white with either browns or clears, that would be top offer at about 90+Shipping for a "like new" and going down from there based on condition, colour, type of board, etc.
TBH i'm not totally stuck on the brand, I just like the colour and look of the leopold in white, as I think white works better with custom colour keycaps than black does, without going over the top.
This would be used for gaming so TKL is almost a must unless you're willing to dump a TK board at an el cheapo price.
