VU+ SOLO2 WI FI USB 2.0 Stick

Hi

I wanted to purchase WI FI USB 2.0 Stick for my VU+ solo2,
I was amazed that the price
Is somewhere 25-30.00 Euro?
Normally WI FI sticks for PC are sold for 8-15.00 Euro in many shops.
Can I use a normal USB 2.0 WI FI stick?
Can somebody advice which USB 2.0 WI FI sticks are compatible
for VU+ solo2 With reasonable price?

Thank you
