Glad to hear it is working, hopefully it will stay that way.
The IDX comparitors are more involved and can be a pain sometimes since you have to program them to the coin/coins you want to use. With the more typically-used CC-16 types you just insert a sample coin and you're done. But the IDX comparitors are more versatile in that they can be programmed to accept up to 6 different coins/tokens, that comes in handy sometimes. For example, you could have a bunch of similar sized but different brand of tokens, the IDX would accept all of them (up to 6 different ones), the CC-16 would only accept one style of token.
