Bought a second hand Russell, it worked ok for me, but I didn't think it was great for me... specs were built for close to me.....
When I ordered my new 15, I bought a set of seats to send to LAAM... had him build me a seat to my specs, I couldn't be happier - called me a few weeks after getting the seat and had it built before I got the new machine. It was winter and I had no delay, nor was I really in any hurry... Maybe I got lucky in the time frame - but he was kind, courteous, and generally cared about getting me what I wanted...
Almost a year later, got an FZ-09 - got a trashed seat off ebay, had it sent directly to him, about a month later - got the same treatment.... bit longer time frame, but I didn't care, am very happy with his product...
Sorry the OP is going through this, but I do think the way to go with LAAM is get an extra seat and wait in line.
Worked great for me.
