Most MK2A/B heatbeds I've seen on ebay have the thermistor presoldered. Not a big deal.
Also if you'll ever damage your glass, you can just get one 3mm thick 20x20 cm or 8x8'' cut somewhere locally for few bucks.
I'd also get 3 686zz flanged bearings in case you'll have friction and will want to replace the 3 back bushings. http://www.soliforum.com/post/74861/#p74861
Print yourself Y axis modded brackets which use bearings too,

And maybe use this if I'll need to upgrade to a carriage which uses linear bearings: http://www.soliforum.com/topic/8977/alt … ng-method/
And if you'll need to upgrade to the MK2B heatbed, you'll need an upgraded PSU and a SSR.

I've found both locally so I wouldn't worry about ordering it just in case to not have downtime when I'll need to.

PLA plastic doesn't have much warping issue like the officially supported ABS.
No backlash issues...not even a mod in that area.
You did just mention you added 3 bearings.
Can you please try printing this and showing your results? http://www.thingiverse.com/thing:532915
It can be hard to notice as the backlash reaches <0.2mm like for me.
Everyone who has told me they don't have backlash issues have noticed they actually do when looking at this print. me too.
I did take the time to do calibrations, etc. as suggested. I also added two fans and three bearings to improve print accuracy.
I find that tweaking bed and extruder temperatures, extrusion rate, and Z-height, can really produce excellent results.
Been there, done that... http://www.soliforum.com/topic/8199/odd … t-results/
Except the fans. Any STLs for that?
