Most high quality step-up transformers (SUTs) or active step-up devices sell for well upwards of $1K, and the lowest price SUT I am aware of that I would give any consideration to costs $750.
I see no reason to go with a low output cartridge in the price range you are considering, or anything close to that price range.
