I was almost completely sold on purchasing PELock because it offers everything I need, however since the support is absolutely horrendous, I've changed my mind.
I messaged the 'help live chat' feature, and when I realised I wasn't going to get a response, I sent an email using the contact form. Only to wait 3-4 days to wait for him to respond to the live chat message (Which I didn't ask any questions in, I just said 'hello, anyone there' basically, but not respond to my contact form email with the questions I actually needed answered, not to mention not replying to this forum.
I get that he's probably a solo developer, so am I, and even though I'm busy, I always make time on a daily basis to respond to my clients. If he can't even dedicate time to pre sale questions, I highly doubt he's going to make time furthering his products.
