I build on Batson Rainshadow blanks but have built a few MHX rods and they are decent for the price.
The kits offer really basic components (full cork grips, full trigger seats, basic guides) which are fine if that's what you are into while learning but IMHO you should talk to a rep with Mudhole to help size more attractive components.
I think their old kits were like that, but now they have kits with many options.

Chrome Fuji
Kit Reel Seat
Fuji ACSM Exposed Blank
Fuji ECSM Exposed Blank

I prefer to build not using the the kits, that way I can use the exact components I want. However, a friend of mine ordered a couple of the kits and for the price it's a great value with good quality components.
