I used to have a blue stripe for 5 years and it's one of the best amps I've ever had. When I tried the mark iv tho I was floored because it has tons of tones and it's super versatile. I sold the mark iii and now that I have the 2c+ srgx I can safely say that people who want the raw mark tone should definitely grab a mark iii for less money. The 2c+ is not as harsh sounding as my blue stripe and it does have something special but then again I wouldn't pay a small fortune for one. I got mine 2800 in mint condition, combo exotic wood plus the road case and shipping.
