I didn't have a timer before I bought my StopClock Pro. It's awesome. F-stop printing just makes so much sense for me. Yeah, it's expensive, but frankly, with the cost of FB paper nowadays, it's about equal to a couple packs. Having the extra channel for split grade printing and the programmable burn sequences is very cool too. I never really printed much before getting it, so I didn't have non f-stop printing ingrained into my thinking. It was very easy for me to just hop on board with that mindset, so for me, it was well worth it.

I don't know your timer. If it's working for you, then stick with it. If not, don't. Maybe sell some of that Tech Pan to fund the purchase
