...I'll second the "Marc two tone - legend" Vibe...not come across a nicer guy. Went above and beyond helping me get my Team Marin forks/stem/bars powder coated...even took them back a few times to get them re-done as he wasn't happy with the result! All for the love of it and wouldn't take a bean for the work done!!
If there was such a thing as a "legend" banner Marc should get one!!
I managed to free a seized Marin Stinson seat post a while ago. I used the vice / upside down frame method with a little WD40 and I had the seatpost out, undamaged, in 30 minutes.
