What's the rest of your system? You've got a *great* cart, your arm is decent, and I'm only familiar with your tt through name. You could throw a lot of money at your system and not (in fact, never) overtake your cartridge. In particular, perhaps your phonostage would be a better upgrade then your tt-at least, a better choice than the two decks you're looking at.
Saying that, the HW19 is a lively deck that might provide some needed PRaT to your system. I don't share the same enthusiasm that you do with the SOTAs but then, that's me.
And don't forget-since you're buying used, you're looking at more of a long term, low-dollar-outlay audition for these TTs than a real purchase-you can always re-sell for *at least* close to your purchase price.
