Congrats on getting a good deal~! >w<)/
I've worked with Clip Studio for almost a year, after switching from Paint Tool SAI. It took me about a month or so to learn it, though I had worked with SAI for around 5 years prior to that so it was mostly transferring knowledge and relearning short-keys. (Which I found out too late that you can change \D)
I've really enjoyed working with it too! I've dabbled with GIMP, Paint.net, SAI and Photoshop, and Clip Studio is an excellent rounding of all those other programs, especially for comic work. It's also very customisable, and for the price, it is reallyy hard to beat. :'DD
Good luck tinkering with your new program~! Have fun learning how to make it work for you!
