Wanted: Front mech for 3x7, Shimano, 46-36-24 chainset

[W4050]

I'm trying to build up a bike on a relatively new frame with an old set of components. The original front mech (Deore LX) is a bottom pull, whereas the new frame needs a top pull mech instead.
I've been looking for a suitable front mech (34.9mm band) that will work with an old Deore LX chainset with chain rings having 46-36-24 teeth. Most of the inexpensive up-to-date stuff I can find either needs a minimum difference of 12 teeth between the top two chainrings, or has a total capacity of only 20 teeth, and from what I gather therefore won't work well with the chainset I have.
An FD-M901 looks to be the front mech I could do with, but they seem to be a little hard to find and so I'd like (if possible) to find a modern equivalent that would do in its place, but am struggling to find something that would work with the components I have to hand. I don't want to spend too much as this is really just a bike to accompany the kids when they go cycling, so it will see no hard use whatsoever!
So, either an FD-M901 with a 34.9 band, or something else that would work with my chainset - any ideas?
Many thanks
Andy

Re:

Got an lx one. It's an m566.

You will have to look up the ratios it does as I have no internet!

Taken me 10 mins to post this :x

Re:

Unfortunately everything I can find suggests that the M566 will only deal with a maximum difference between the top and bottom chainrings of 20T, whereas mine is 22T and has a maximum large chainring size of 42T, whereas mine is 46T.

Following a bit of thought, I'm going to put the project on hold for the moment and may look for some other components to make the selection of things like a front mech a little easier!

Re:

Both XT M750 and Deore M510 will work. Both were available with a large chainring version at the time and Shimano never produced specific mech's for either.
I worked in my LBS when these were current, and often fitted them to hybrids at the time. If you can find any archives of the Dawes discovery range almost all of them had the Deore with the XT on the top model
