Hello, > METCAL MX500S Rework System (Smart Heat RF technology) Buy it! This is simply the best soldering station on the market. It IS expensive, but it is well worth it. The tips are expensive, but they seem to last forever. As far as tip go, everyone has their favorite. I like to use the STTC-144. I ust it for ALL smt work I need to do. I use a STTC-137 for ant thru-hole work. Duane -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
