Why would you want an underfolder?
IMHO they are a pain in the ass and uncomfortable as hell to shoot with, I am assuming you have never shot an AK with either otherwise you would realize how much better the cheak weld is.
The handguards are better than wood and will be more insulated and not get as hot as wood. There is a steel guard that reflects heat off of them. They are much more durable then wood.
If you want accuracy, get an Ar-15 or bolt rifle. The AK doesn't have as tight of tolerances as either one of those, that way it will function well in the sand, muck and everything else you would be afraid to throw your AR-15 into. The accuracy will be better than a 7.62 x 39mm which is good enough for plinking/zombie killing.
Who cares how long it takes, I would rather them take their time and do it right. I couldnt imagine the wait being more than a month
