Resonably priced flexible adhesive

[kinhell]

I need to tile 36 sqm and need a flexible tile adhesive. I know Bal is recommended by the guys on here but it'll work out expensive. I was wondering if there is anything out there which is more reasonableand does a decent job? I've seen excel but not sure if its any good.

What flexible adhesive do you use and what sort of price is it? Where can you buy it from also.

I used to use granfix which was £18 for 20kg but now use benfer which costs me just under £14 a 20kg bag (trade price)Have had no problems with either so far.
