About 6 months ago,

Yep i use it almost exclusively.

I like Simplify and don’t regret the purchase. Overall, I find it a good package. I think it’s short sighted to try to weigh the price on hypothetical saved filament, because there’s so much more to the package. It still has some issues, but overall it’s a nicer, more seamless bundle than any combination of the free software I’ve seen yet. I like that I can load a .factory file and it recalls parts, custom supports and material profile and fine tuning exactly as I left that file last time I used it, so a year later, I know how I built said part.

I think it’s really shortsighted of the company to not have a demo version though. I’ve seen way too many people express interest but skittish about buying without any ability to try it first.

So I bought my copy last night. All I can say is WOW!! So many options, so much tweakability, and a nice interface to boot! It took a bit to figure out how to use it, but well worth the time (it was only ~30 min or so). Great tutorials on their site.
I typically stick to opensource software, but sometimes a product comes along that is worth paying for. This is one of those products!
Thanks everyone for your input and helping me make the decision to purchase this software.
