Nik,
Well it all depends what your tastes are and if you want to live in Spain or expat Spain.
I am not knocking expat Spain, lots of people like this and enjoy their life here.
Quesada is a expat area with all what you will need including good internet, it also has lots of bars, lots of English shops and a very good fish & chip shop. However it also has a lot of visitors in the summer that keep the local police busy and it also attracts more robberies than other areas. If you like being close to everything, this is the place for you.
Rojales, Quesada is part of Rojales but Rojales real is more of Spanish, a better bet if you don't want to be too close to all the bars.
Almoradi is a nice town not far from the other two, typical Spanish as is lots of other close by towns.
For internet connections, consider in town for ADSL by Telefonica or others, but you will get very good Wimax type internet in the countryside from Comenersol and others (avoid Aeromax though). We have lived just outside Albatera for six years now and loved every minute of it, we can enjoy where we live, enjoy going out and return to peace and quiet when done.
In the end, it is up to you but choose carefully and make sure it is fully legal if you are buying.
