That seems like a good choice to me. The MFW-15 may cost less (especially the assorted open box and B-stock deals they've been running in recent months), but I haven't heard of LFM's routinely requiring customers to re-do wiring to fix hum, replace multiple bad amps, replace drivers, deal with stripped or missing screws on the drivers, or some of the other QA issues that have plagued the MFW. The LFM's also come with a user manual - rash idea, I know, but after over two years of selling the sub AV123 has still not posted or printed a user manual for the MFW-15.
