Sealed Beam replacements

Suggestions please for the 5.75in sealed beam replacements, I would like something with a replaceable bulb. The mass produced sealed beams are crud!
I think Hella have some but still what are people using or suggesting?
Thanks

I put the Hella H4 conversion housing on my 320i. They are great and have a good projection pattern of light. I put some PIAA non-street legal bulbs in mine, 100/150 watt and while still on low I wash out cheeper HID systems like the ones on Cadalics and some Toyotas I can take some pics of them if you'd like, some day pics and some night pics with the lights on low and high.

Thanks for the info
What were the costs and where did you get them?
I have seen some replacements on EBay but they seem to be cheap knock offs of Hellas

The PIAA bulbs were $52 each and the Hella Housings were $45 each. Since my work is a Hella retailer I didn't have to pay shipping. I think BMP Design sells the housings for the same price you just have to pay shipping as well. I bought some of the knock offs from ebay a while back and the lens cracked from the heat of the bulbs so I would not recomend them unless you only plan to run a 55 watt or lower bulb in them.
