TLR: One lens only, but an excellent one, plus robust and not too heavy cameras. Except when you go w the mamiya tlr, where you have interchangeable lenses but heavy stuff. Price should be lower than RB or Hassy. You can buy an excellent performing tlr for 2-300 $ already.
6x6 SLR: Hassy is just ONE choice, the expensive one; you have rollei, bronica, you have kowa, especially the kowa is a good quality for the price they go for.
6x7 slr: RB and such are considerably bigger than 6x6 slr or tlr ones. Here at least, in the Netherlands, they are not cheaper than tlr's - far from it.
Finally you also have rangefinder 6x6's and 6x7's, with famously good lenses (fujis, mamiyas). These might be the fastest to work with, and certainly the most lightweight (if there's soimething like that in medium format).
Any of these will give you much much better results [technically] than your Seagull.
