A [http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=ASUS+MeMO+Pad+FHD+10+glass&_sop=15|quick look] at eBay shows that replacement screens/digitizers/LCDs cost '''upwards of a third''' of what you spent on the tablet. Kinda pricey IMO.
If the tablet means a whole lot to you, then by all means, get yourself a replacement screen!
To me, it's just another one of the zillion Android tablets models out there. I'd just sell it online to someone willing to pay that much to replace the screen, and find another Android tablet.
It's really up to you... this is just my two cents.
