I see brand new 200DX units with pulser and coolmate 3 on ebay for $3950, and brand new 250DX Tig Runner, with pulser option and same size cooler for $4472, both delivered to my doorstep.
My question? I've got an older syncrowave 300 right now, which runs fine, but I'd like to step up to something newer, with pulser. Are the TIG runners worth the additional $500? What are the main differences between these two units?
Thanks,
Dan
