I do not know where you are located, but craigslist in your area may have hybrids for sale. Assuming that you want to try full loaded touring be sure that you do not buy a bike so big that you can not easily mount by putting your foot over the top tube, (A common mistake), as apposed to swinging your foot over the rear wheel, which becomes significantly more difficult if you pile stuff on the rear rack. I suggest that you have 9.5" seat/ post sticking out of the frame. Most hybrids have the necessary mounts for racks, well 'cept for mid fork for front low rider, but a threaded u bolt works in a pinch. ( If you go that far.) I am against the notion of buying some unwielding, gigantic frame for touring , because the head tube is taller. There are plenty of tall stems on the market.
