3.3V relay issue

I'm designing an embedded control card with a 3.3V microcontroller. Are there any relays that can be controlled by 3.3V DC(our standard microcontroller's output voltage)? It will control a line of 220V and 5-10A. I already know that I can design a circuit with 5V/12V relays which are triggered by 3.3V gated transistor, however the problem is, this design shouldn't contain 2 different supply voltages(like 3.3V and 5V) from SMPS.

What would be your optimum solution about that issue? Price is very important cause the thousands of products will be produced.

There are a few, like an Omron G6RL-1A DC3, under $2 qty 1k.

Howdy, I'd be leery of a very low power relay switching that kind of power without sticking troubles.
If switched power is AC: An alternative is a zerocrossing triac driver optocoupler, 3.3V @ ~10mA should fire it fine. The triac is then sized for the load. G.H. <<<)))
