This is for Europeans mostly. Europe's superlative provider of astro gear, Teleskop Service, has nearly always the best price on anything but at times they beat their own performance with even better pricing; these sales are labeled "AKTION" and often go on for many months.
At the top of their incredible deals is a 102mm (4-inch) triplet apo with FPL-53 glass. Used to be 1.500€, went down to 1.095€, now up to 1.195€. With 3-inch Crayford "Auszug" for large sensors.
A 2-inch diagonal mirror for 45€, 91% reflectivity of course, not 99%, but still a great deal.
Good 20mm 70° GSO ocular for 36€, who'd have thought that possible? (they also have a 15mm)
A twelve-inch GSO dob with 94% reflectivity mirrors for 599€; I paid 675€ for mine. The ten- and eight-inch models are also on sale, the AKTION has been on since June.
A 120mm Sky-Watcher achro for 430€, Celestron's equivalent costs 530€. I suggest making aperture masks of 110, 100, 90, 80 and 70mm to deal with turbulence and chromatic spread.
Delos eyepieces for 293€, they all cost the same whatever the focal length:
(I forgot to choose the english versions, if you don't read german click on the british flag on top of the Teleskop Service pages for translation).
Despite their great deals, they're sometimes beaten by other sellers: Unterlinden of France proposes the EQ-3 mount at the same price (199€), but their version has the steel tripod instead of aluminum.
And, saving the best for last, another german outlet, FERNROHRLAND, proposes an Astro-Professional 115mm/800mm triplet apo for 1.199€ instead of 1.799€, an incredible 2/3 of the regular price. This triplet has FPL-51 glass, slightly less efficient than FPL-53 but lab tests (by Wolfgang Rohr) and photo/visual trials (by Italian reviewers) concluded it's a finely resolving scope. The only other 115/800 triplets with superior glass are german APM scopes with prestigious russian optics, and they cost at least 4.100€.
