VV is having a sale 12% off there DLE's now.That brings the price of a 61 to 400.00 complete,verses 650.00 plus muffler for DA.If you compare the DA and DLE 60's,the DA will spin the same prop maybe the most 100- 200 rpm more.But it won't be as smooth running.DA may run longer without being rebuilt.I have two DA's and three DLE's all of the DLE's have been rebuilt.One DA had been totally rebuilt after the cylinder base bolts broke and I never had the cylinder off that engine.I like both that's been my experience with them.If your a engine guy and like to do your own work DLE makes sense.I never tried but can you buy DA engine parts and work on them yourself?
I should say to that DA did a complete rebuild on my engine and the only thing they reused was the cases at 0 cost for me with a engine that had a LOT of time on it.
