I suggest you try the Surplus Shed and buy a Jeagers 4" F15 lens for $100 and then get some tubing and focuser and get crafty. Otherwise, you will just have to go without.
Sorry, but it is the sad truth. Well, unless you get lucky on Craiglsist and find a great deal.

Johann, this is 2013, the piece has gone up. I just bought one of the remaining Jaegers 4 inch f15 lenses two weeks ago. It was a premium and not a second and it was 150 bucks, sale price with 30 percent off. Regular price is ~225 and they are going fast.
That's interesing Terra. I ordered the 103mm Jaegers objective, SKU L10607J, from Surplus Shed on Friday 1/25. My price was $149 and I had a code for 30% off.
I look now and that SKU is unavailable. I've not received any notification of it not being available, but I've also not received a shipping notification.
My goal is to make my own F/15 refractor.

Then if you can build a long, square box, or get a piece of metal tubing that fits the focuser and lens cell, you are set to go. (Still need a huge mount of course).
Do some searches in the ATM forum and you will find a lot of options.

we are going to get slammed soon for being out of context for not talking about classic telescopes.
Maybe not. You're lamenting the lack of new scopes built to classic standards, and trying to find a solution. The fact is that not everyone can find or afford a 4" Unitron, but many of us aspire at least to the optically equivalent experience.
Long-focus scopes are way under-appreciated. Their views are prettier at lower cost, they hold focus better in compromised air, and they are happy with simple, inexpensive eyepieces. If you can find a modern solution to the problem of the world's limited supply of classics, more power to you. "Classic" as a set of optics and a state of mind is valuable in itself, even if the scope is new and the label won't read "Nippon Kogaku."
Cost is a legitimate concern. Skylight Telescopes are perfect, but beyond many budgets. S&T published a glowing review of that scope from Hands-On Optics, emphasizing that the price was not a misprint.
This is, incidentally, why I jumped at the chance to buy my Tasco 7TE-5 recently. I understand that 60mm of aperture won't show me everything I could possibly want to see, yet I anticipate that what it reveals will be shown with exquisite beauty.

looks like antares is still available outside the USA
Khanscope does not have the best reputation... Check out the message on the Skylight telescope site for an example.
As well I contacted them about a year ago about these and they had no stock if I remember.
