The SS series Beemans are Chinese copies of rifles made by Norica of Spain. Oddly enough, Beeman also sells the Norica rifles under the GS and GH designations.
The Spanish (Norica-built) Beemans are the GS950, the GS1000, and the GH1050. The primary difference is this - the GS950 has a plainer stock and a weaker powerplant (I suspect it's similar to the old S1) but (I think) a very decent trigger mechanism. The GS1000 had a larger powerplant and the good trigger. The GH1050 also has a strong (maybe stronger) powerplant - but a rather poor, "direct-sear" trigger that breaks at around 6-7 lbs and is non-adjustable.
The Chinese copy the last two rifles - the GS1000 and GH1050. Their copy of the GH model is called the Beeman SS1000 model 1050H, and their copy of the GS rifle is ALSO called the Beeman SS1000 (with some other model number). How can you tell the difference? If the rifle has a "two-stage adjustable trigger", that's the better one. If the trigger is NOT adjustable, that's the model 1050H... and do NOT believe the garbage about its having a "two stage" trigger. SOME RETAILERS DON'T KNOW THE DIFFERENCE! I know, because it happened to me... what I ordered was described as having the better trigger - what I got was the crappy one. Overall, it was a lousy shooter and I was able to return it.
Now, the better Beeman SS1000 is ALSO sold under 2 other brand names. It is sold by Compasseco as the TF89 for something around $160, but it is ALSO sold as the Industry Brand AR1000. THEY can be bought from
http://www.dauvensfishinhole.com for about $82 (either caliber). It can be a very decent rifle for the money - BUT if you get a bad one from Dauven's, there's virtually no service or parts support. This does NOT apply to the Compasseco or Beeman variants - and I suspect that's why they're more expensive.
The Norica model that is sold as the Beeman GH1050 has also just been introduced by Umarex USA as the "Hammerli Storm", and is available from
http://www.midsouthshooterssupply.com for about $132 (which, incidentally, is about $40 cheaper than the Beeman version). Umarex USA is essentially RWS USA, so warranty support is there. I've got one of these in .22, and it is a very good rifle - if you can live with the trigger. I can tell you that the Hammerli is better made than the Chinese copy (SS1000 1050H).
If you scroll below, you'll see my reviews for the Hammerli Storm and the AR1000. If you can afford the risk, the AR1000 in .22 is tempting. If you get a good one, it should satisfy your needs for both power and accuracy. Otherwise, the Storm is a safer bet - if it had a better trigger, it would be a fantastic rifle for the money in my opinion.
