Man; go for SII. I have experience on both and SII is way more faster than SDuos. Processor makes a big difference while using applications.
S Duos does not handle applications well, hangs a lot, less responsive than SII and Android V4.0.4 is also not stable. If you see Android market share, GB is still king being stable, uses less power than ICS and no OS bugs. On the other hand, ICS still developing slowly.
Also key board in S Duos is hard to use being on less screen area.
Simple is if you really need dual sim function, go for SDuos. Otherwise believe me SII is the ONLY option you shall go right now from Samsung.
For cheaper options, try some other brands with same spec (LG, HTC, Lenovo etc) but they dont have good market in Qatar. Also use this www.gsmarena.com
