This is hard to tell: your perception of value is different from mine, and different from everyone else. I suggest to go through every function in the spreadsheet, note all features you want done, and then look at chosen features as a whole and decide how much they're worth to you.
As a bonus...
it was super easy. grab a windows laptop, buy the forscan license onlie, order the recommended dongle and follow the spreadsheet. I programmed the seatbelt and auto up/down for my windows in about 10 minutes. Easy peasy!
