I am not really 'looking' for one . . . I got the 248, and came to the vintage section, and now I am obsessed!! So, of course, I went and played on c/l, and found the 600. Now, there is a 15-91 also, with a large cabinet for $150.
i have ebay set to cheapest first, which I just realized is why it is taking me so long to see a 301!
Are those two just good solid machines for vintage ones?
