Good, powerful bullet vibrator for penis stimulation?

Hi all, I'm looking for a recommendation of a bullet vibrator with lots of power for "handsfree" penis stimulation!

I've recently discovered that a bullet vibe, when strapped to the underside of my penis head with a cock ring, can give me a very enjoyable "hands free" orgasm. The only snag being that it can take a while to come this way! I think I need something that vibrates hard but at a lower speed, if that makes sense; the vibe I currently have (Whisper Micro Heated Bullet) vibrates at great speed but without a great deal of force.

Something more potent would be ideal, and I like the idea of the multi function vibrators that pulsate as well as the usual variable-speed vibration.

It must run on ordinary batteries - i.e. AA or AAA as I have rechargeables in these sizes - rather than the little button cells or oddball "N" sizes. So far this Pocket Rocket (http://www.lovehoney.co.uk/product.cfm?p=15359) looks interesting in terms of power and multi-functions, although I'd have to aim it manually rather than just strapping it to my erection with cock rings! But, if it reduces me to a quivering, gibbering wreck then I'm all in favour...

I got a bunch of the ones LH give away free. you could always strap multiples of them on. Infact. I might try that tomorrow!

I'd suggest this- http://www.lovehoney.co.uk/product.cfm?p=22081 It takes 2xAAA batteries and has 3 speed variables and 3 different patterns.

There's an amazing offer for blog readers- http://www.lovehoney.co.uk/blog/ On the right link of a free gift it links you to this powerful firecracker that takes 1 AA battery. http://www.lovehoney.co.uk/product.cfm?p=17063

You have the choice of the VibraExciter toys for handsfree fun! You just need someone calling or texting you. There's the "female" bullet version http://www.lovehoney.co.uk/product.cfm?p=2216 and a male cockring version- http://www.lovehoney.co.uk/product.cfm?p=13354

Good luck looking and have fun! There are some sleeves/strokers that actually vibrate as well. =]

Thanks Eskimokisser and Nymeria

I've ordered the Tracey Cox Super Bullet (http://www.lovehoney.co.uk/product.cfm?p=22081 ), plus the free Lovehoney Powerful Pocket Vibrator (http://www.lovehoney.co.uk/product.cfm?p=17063). I also added the Crystal Clear Mini Vibrator (http://www.lovehoney.co.uk/sex-toys/vibrators/classic-vibrators/).

Now all I hav to do is wait for the parcel to arrive - I have batteries on charge in readiness!

My new toys arrived on Friday, and they've been thoroughly tested several times over the weekend!

The Super Bullet is brilliant - strapped to my cock with a couple of rings and set to one of the pulsating modes, it had me exploding in my PVC French knickers after a few minutes :)

The Powerful Pocket vibe is good for spot stimulation, especially when the Super Bullet is doing its thing strapped to the underside of my erection; the Pocket vibrator feels great on the other side of the head.

And finally, the Crystal Clear vibe is simple but effective, giving nice strong vibrations which, if I grip it between my thighs against my perineum, feel great on my prostate!

All three at once is a hell of a sensation, especially when dressed in something on the slutty side of feminine! I think I'm developing a handsfree orgasm addiction though... ;)
