Suggest a second monitor/screen for my laptap?

I found this one Lenovo ThinkVision LT1423 but something a little cheaper I would appreciate. Touch screen is a must and wireless connection to laptop highly favorable but not required. Also I would like a wireless keyboard too.
Also this is just cause I don't want to spend another 1200+ on a gaming laptop for school that has windows 8 on it. Their are no touch screen gaming laptop yet custom or retail. From what I researched those will not be available till near the end of the year(of 2014). So this is the supposed solution that I came up with, just not going to open the lid on my laptop for anything other than the power button.

Here is my laptop if info is need about it. - http://www.newegg.com/...6834152369 - it discontinued 2 weeks after I bought it, because they moved on to 4th gen intel.

Added (1). mimomonitors are small wow. Anything else like conversion kits.
