Tesoro fan here...
Howdy, you did say that you were open to other suggestions as well...
Big fan of the Tesoro Silver uMax (around your price range) as well as the Tesoro Compadre (well below your range).
Have both, enjoy the heck out of both. Lol.
Could right a book on why, but if you google search for Tesoro Silver uMax Reviews... its got awesome reviews as well does the Compadre.
Silver goes a bit deeper than Compadre, both have lieftime warranties, Compadre will hit a bit harder on tiny gold. Silver can exchange coils.
Yes, they are not TID machines, but either of these machines will indeed start to "talk" to you, lol, after some use.
Both have fantastic battery life, they each only take 1 9 volt battery, both are very lightweight and can swing for hours. Both have found me small gold earrings and the smallest toe ring, lol.
I'm sure the other machines are awesome as well, but I can only attest to these. Never been sorry I made these purchases etc.
Anyways, just thought I'd throw them into the line up for ya.... try taking a look at the reviews, and there are tons of them, folks seem to really like these machines. I know I won't be without either.
Good luck, all fine machines.
Have fun.
