Slightly stuck, new combo box or a DVB-C tuner needed?

[roadie]

Hi.

I hope someone can help.
I have a XTREND ET9500 satellite box, I was looking online and I notice that it has a plug and play cable tuner such as this one: http://www.shopping4satellite.com/xt...ner-dvbct.html

My question is, is it simple to do or does it need some kind of technical expertise as I don't know what it entails. Alternatively, would I be better off getting another combo box such as a Zgemma h1?

The 9500 has 2 Plug & Play tuners they literally do just that, you unscrew the little small black screw then just pull it out and replace with your DVB-C/T/T2 tuner
