Same tbh. I use a Plustek 8200 and the inversion and adjustments after the scan was never an issue for me. It's the 1.5-2 hour block it takes to scan a roll and having to baby it the whole time.
I was just looking into the finally released Knokke 135[1], and it seems promising as an alternative. Seems to be the only option that is both fast, has IR dust removal, and doesn't cost an arm and a leg.
