Yes, I would go with a Razorcut or an Everlast. PT60 style torches have reasonably priced consumables as well. You are looking for a plasma cutter with a “Pilot Arc.” Check your local craigslist for cheap used plasma cutters as well. HF units are getting harder and harder to find (good) so just make sure it is a pilot arc ignition.
Under no circumstances should you even try one cut with the High Frequency machine, you will fry the electronics enclosure, probably on the first ignition.
