I don't think that someone who is serious about their keyboards will like someone touching their keyboards... It is like someone effing your virgin girlfriend (seriously)
If right now you don't have the money, even if you like it, you can't own it. After buying the Leopold, you will probably prefer the Realforce, so, you have to sell the Leopold again and save up for the Realforce... In the end, you lose money...
My suggestion is that you can try to buy the Realforce in the geekhack marketplace (someone is selling 1) or buy the Leopold. If you do not hate it, learn to love it.
