Alternative to Shimano SF-MX30?

What are alternatives to Shimano SF-MX30? I would like 15T as well, as 16T is a bit too low gearing.
Is changing 3/32 single speed to 1/8" single speed a simple affair? Just change over chainring make sure I get correct BCD, chain and sprocket, chain lines will be equal, no spacers required?
With 1/8" is there more variety in sprocket chainring, ie there are chainrings in 1 tooth increments, wheras 3/32 has less?
One of the bikes has a "formula single speed kit" which I assume is a regular cassette freehub with a spacers to convert it to SS?
So all I need is one of these (pretty cheap) in 1/8

What is the smallest recommended sprocket to use (so have good chain contact)
then one of these

However if a new quality freewheel is this expensive..

SF-MX30 is a freewheel, the above is a fixed sprocket
Never heard of Token freewheels, why not spend a few more pounds and go for a White Industries freewheel?
16t is the smallest freewheel you can get on a hub, you can get juvenile hubs which are smaller and intended for kids bikes but 14t is a common size. Why not go for 16t and a larger chainring?

£73???? wtf

Look on Ebay, you can find them closer to £50 if you strike it lucky. Worth it IMHO, you can service the freewheel easily and new parts are available. I fitted mine before Christmas and it's been faultless in the 3000 miles I've ridden with it and it makes a nice loud noise too, I've approached peds on cycle paths and freewheeled and with no sound from me other than the freeewheel they've looked round just before I was going to make myself known and moved aside for me.
If it's whole new unit, then it's going to cost far more than a cassette!

New sprocket ring for £35 from CTBM was the first link I clicked, probably cheaper elsewhere.

48/16 with 28mm tyres should be ok.
Stock gearing is 46/18, unsure what tyres are on it I'll see if it's too low. If it is I'll think of whether I'll get a 15T freewheel, or stick to 15T fixed (very cheap) Until I wear that out then change the lot to 48/16 1/8"
