Back in '99, I bought my '77 Fender Jazz bass from them, and earlier this year I got my Martin Style 2 from them as well. When I ordered the Martin, they actually had 3 Martins that I was interested in. I spent about 1/2 hour on the phone with someone there, who was VERY helpful and patient while I narrowed it down to one uke. He played each of them for me over the phone, gave me his assessment of sound, condition and playability, and then actually recommended NOT THE MOST EXPENSIVE of the three (!). The shipping (both on the bass way back when and the uke this year) was flawless and really fast. I was totally satisfied.
Also, about 12 years ago, my neighbors up the street (who are excellent Bluegrass musicians) were in the market for a Martin acoustic, and were passing near East Lansing. So they stopped in, told the staff they were looking for a Martin, and were basically allowed free rein of the entire guitar room for as long as they needed. No one pressured them... they could play EVERYTHING (including D-28s from the '30s and '40s). They played all morning, went to lunch, came back and played some more, and walked out in the mid-afternoon with a brand new HD-28. They RAVED about the store, which is partly why I bought my Fender from Elderly the following year.
I've never heard a bad thing about them!
