I am pondering getting my S2 milled for a dot and wondering what people's thoughts are on the various options for milling? CZC has their own plate system which is nice but that is $275 vs SBGW who has it listed on sale for $134, primary machine is in the middle at $180. I could also just get the S2 OR and sell my current one. So basically I am waffling and soliciting opinions.
