ive got a cheapo GMC one and it works great i used it to taek my brazed together linkages apart ,by cutting away at the join ,i did this so my linkage rod didnt get damaged by the oxy

also ive used it with a little wire wheel to clean carby parts ,when removing old gaskets ,i lightly bued of any left over gasket instead of using a paint scraper

ide by a cheap one and if it breaks buy a better one ,no need to spend hundreds of dollars on a tool that wont get used all day everyday

good luck !
