I think of APs and TECs as pretty equivalent in quality, the difference being though that the TEC waiting list is considerably shorter than the AP - unless you know you are right near the top of the AP list you will literally be waiting years for your scope. I can't recall what the current wait is for the TEC140 but its usually around six months, though it depends on exactly when you order with respect to their production cycle. Sometimes the larger TEC scopes can be bought on much shorter notice though, either because the demand is less or because TEC produced more of them in a production run than they had orders for. Right now for example there is a TEC200ED that is sitting there waiting for a buyer.
TMB in the USA was selling a TMB130SS scope but I don't think any more are being made until some issues about the estate of the late Tom Back are sorted out. APM in Germany (who were TMB's partners) do make their own line of APOs using TMB designs and Russian glass but they tend to be pricey. Another option is A&M in Italy.
Tak scopes do tend to be expensive and heavy for their aperature but the advantage is much shorter delivery times and local support by the Tak dealer in Australia. Tak build and optical quality is extremely good.
The other option in this aperature range is the WO FLT132, which is what I ended up buying because I didnt want to wait (no wait period when they were first released) or pay Tak prices. But that now has a wait of about 6 months from what I last read.
PS: another option are the TV imaging scopes, like the TV NP127is. These are light, short focal length and optimised for imaging. You can buy them via Bintel but they are not cheap.
