TomTom go 730 or go 825 live

I have a go730 with a broken digitizer(?) is it worth fixing that or should a buy a second hand go 825 live for 20$.
The map I'm running is the latest Euro truck.
Are there any prose and cons with the 825 or the 730?

Sorry for any spelling errors or bad sentences, english is not my first language

I would try to find a reasonably priced second hand device, the price of a new screen will not be amiss if available

Do you know If I can download maps from this site and use on the 825 live? The same way I do with my old 730.
