Panasonic 3dtv from amazon, is it a best buy?

Morning All,
Today I am looking to save money from the internet. I have been looking since before xmas for a 3dtv. i have just found a plasma tv on amazon and it is a Panasonic plasma tv   
Panasonic TX-P42GT20B 42-inch Widescreen 3D Plasma TV with Freeview HD and Freesat HD (Installation Recommended)
this seems like a really good price to me except there is no glasses, but i am still unsure as they cost between £60-100. Also I am still debating which is better plasma vs lcd and which is the best buy? 
I still have some questions, please could the readers get in touch and let me know your opinions?
Are Panasonic plasma tv's a best buy?
