I can't really get a good gauge on how much these two Famicom games are:
Deblock (published by Athena)
Doki! Doki! Yuuenchi
Not looking to buy right yet, since I'm trying to finish my NES collection first, but would like to get a rough idea of what these are going for currently, since I'm having a hard as hell time trying to get any price info on them.
The other estimate on Crazy Land is low. If you see it for $15 - $20, it's likely a BIN from an unknowing seller, and grab it while you can.
I'd say $40 or so is much more the reality on this one.
