New? Used? What sort of detecting are you going to do? Land? Water? Salt water? Relics? Gold nuggets? Since you look to have one already, you know the answer to most of these questions already. For others, generally, the Etrac is older technology compared with say an Equinox, Manticore, Deus 2, Legend, etc. That doesn't mean that it won't work just as well under certain conditions. It's a lot heavier than the new machines, so, sometimes a sling in desired to swing one for any length of time. The processor in an Etrac is slower than the newer machines, so, target separation is harder to attain. It's also not waterproof. I do like the Etrac's dual I.D. numbers however. If find it easier to tell junk from good targets. It's also still one of the best machines for deep silver too. That said, mine mostly collects dust since I got the Equinox and Deus 2.
