You're correct that "full treatment" does make a big difference.
Regarding the OP's point as to the best value... I may have misinterpreted that as to include (lowest cost = greatest impact) as part of that "best value term".
Regarding a Spin-Clean. Based on what I've read and seen in print, I'd go with the Gem Dandy over it, mainly because in the (initial cleaning), the dirt/crud that comes off of the record won't go into a bath that the next lp will see.
