I have found a company that supplies similar boxes called Weston Boxes and also a company called Easy Foam that supplies to pre-cut inserts.

By marrying the two this may be a solution.

I do not know if these are the companies that John used but it perhaps is a way forward to obtain boxes at a reasonable price.

Can't really comment on the spec of the motor being largely ignorant of such things, but I did get one of these latest releases to add to an earlier 101 release and a 108 and are all smooth, quiet, excellent runners

I've seen the advert for this new model and note that it has a 3 pole motor. I know nothing about motors, but other new models (including Dapol)seem to have either a 5 pole or  a coreless motor which are claimed are an improvement on the 3 pole.

Is the new model worth buying with what I guess/perceive to be an inferior motor?

As I understand it the pre-existing product is a single shelf one - effectively replacing a gradient, as a means of getting a train to a different height, rather than a complete storage system. The new one has the 12 roads and is therefore a proper storage system (and comparator to the Nelevation). I imagine the price will be rather higher than the ~£500 for the current one.

Appear to be 2 different sizes & available to purchase...

I agree with ntp on all counts. At the moment few can answer any of that!

I certainly wouldn't let the failure of Nelevation cloud my opinion of the Proses offering, they're wholly different products. A lot of the Proses products feel like a sledgehammer to crack a walnut, or a solution in search of a problem, but I can see the appeal of this.

I have half a dozen of Jon's boxes/liners and find them hugely useful, although the foam has a penchant for chomping on NEM couplings so I put all such in polythene liners before placing them in the foam. Whether Jon continues to trade or not I wish him well in recovering.
Thanks for the info, Bob.

Wonder if it's this one

I've checked your posts going back to last December and can find no post that's been unapproved.
Likewise I've gone back through all deleted threads to last December and cannot find anything related to an HO item. I'm not saying it didn't happen, just that I can't find it.
The Angry/Happy/Unhappy threads are for anything and are not railway (real or model) specific.
One complaint is always considered on its merits. More than one complaint can, and does, result in removal of the post/thread.
If it happens again, please ask the Mods why. We're not here as judge, jury and executioner but to maintain the family standards of the forum and, yes, apart from one I know, we are human

As it's not available yet nobody except Proses can answer the specific questions and who knows about long-term reliability?

Proses seem to come up with a lot of products, some seem to be good ideas.  I've not used any of their offerings myself.
