I speak for no one but myself - I'm sure many will pay those prices :)
On a separate note... Every so often (once every 3/4 months) I have occasion to use litmus.com to test an email template for a freelance gig. They only do monthly plans too - plans which I'll never be able to justify paying. I'd be happy to pay a one-off fee every time I needed it but they won't offer that pricing model, the end result being I cycle trial accounts through my many email addresses and they miss out on revenue.
It doesn't sit well with me because their sole factor of production (like yours, I imagine) is CPU time which is pretty well commoditised nowadays, so offering anything more complicated than a single unit of the product immediately tells me that artificial barriers have been created with the sole purpose of extracting "extra" money from me. It kinda grinds my gears.
Hmm... I hadn't considered that view before, but I can see where you're coming from. The intention (for me) definitely isn't to extract extra money. Rather I'm hoping to provide something that provides enough value that it's a core part of my customers workflow, and worth using every month. I honestly hadn't given much (any?) thought to trying to do one-off documents until you suggested it. I'll definitely be mulling it over.
