I'm looking at perhaps purchasing my own stringing machine as I break strings quite often and I've realized that adding together the price of the stringing service has already piled up to half the price of a cheap stringing machine in just a few months.

I've never strung a racket before and was curious what machine people would suggest. I've looked at the beginner sticky thread already and I'm kind of confused with the suggestions (for example, what's the difference between Eagnus Challenger I and ST-200? They are the same price and both are suggested as a beginner stringing machine on the thread)

I'd also save a lot by buying string in reels online than from buying the string from the store and having them string it for me.

Any suggestions as to what I should look at?
