What are you unhappy about?

As the other post said, it depends on what's bothering you about the chain you have. I still have 8-speed on a couple of bikes, though, and I've used SRAM chains for three or four years because I don't like to fool with that stupid Shimano pin. I think the 8-sp SRAMs are the PC-48 (cheap) and PC-58 (a few dollars more). Both work fine, no pins to lose and you can remove and replace without tools (I've heard that's hard to do, but the few times I've tried it, they've just come apart at the connecting link without any trouble).

Thanx, but i have find what was the problem. Chain was not connected properly so one of the link was stiff and that was it. I will have to talk with the guy in shop who assambled the bike :-))....and yeah one more thing, the guy in the shop told me that after the ride i should lower the pressure in the tires when i`m done with riding the bike for 8-9 hours(night time i guess) beacause the tire will crack all over. So should i do this or what? Thanx.

Apparently your bike shop doesn't have the skills to install a chain properly and is full of BS about tires. Perhaps a new shop is in order.

Thanx very much in fact that bike shop is ok but the new mechanic guy is stupid and i think he is into freeride or something like that. I also have to adjust gears by myself but the bike is great and i love it. This is my first road bike, nothing special Caprine SpeedMax1000 and it`s realy light for 435$ (9,5 kg) I will post picture soon.

It shouldn’t matter if the guy is a mtn biker or roadie. A chain is one of the most fundamental (and simple) piece of equipment on a bike, any mechanic should be able to set one up without any problem. The same goes for adjusting the gears. If a mechanic can’t do the simple things, imagine what would happen if you run into a serious problem. Personally, I wouldn’t trust my bike to someone who can’t do a simple tune up.

When pushing a pin back into a chain, the link will be stiff since the the chain is being compressed while the pin is being driven through. You can work the stiffness out by horizontally flexing the chain back and forth or using the second set of "stops" in the chain tool to spread the external links out a bit. This is about as fundamental of a mechanic skill as you can get, aside from changing a flat and I'm surprised this person didn't know that.

Also, regarding tire pressure, it was customary back in the days of sew-up tires to deflate them a bit after your rides to keep the casing from stretching since their casings are wider (continue back to the center underneath where they are stitched rather than ending at the bead of the rim). Also, the more expensive sew-ups were/are made from silk and weren’t designed to handle pressure for 24 hrs so you would always let some air out after a ride. This has never been a consideration for even the best clincher tire, not even 20 years ago. You should still pump up your tires every ride but only to replace the 5 or 10 lbs you usually loose every 24 hours.
