I've owned at leasr a half a dozen of these things... The one I probably should have kept was a flat-top Gibson from the 30's because it had more umpft than the Martin 0-17, the Harmony arch-top, the Harmony flat-top and another one that I can't remember... But I saw a 30's Dobro resonator tenor on ebay but was outbid and so I contacted the buyer and he wasn't really looking for a rosonator so I traded my 30's Gibson for the reso... I like the reso okay but it ain't got the umpft as the Gibson....

BTW the Harmonies aren't all that expensive... The flat-top has more umpft to it than the arch-top if that matters to you which unless you are just playing by yourself doesn't much matter but if you are playing with others than the flat-top will hang better..
