A few things:
If you get a chance, use the SEARCH the FORUM feature near the bottom of all these postings. Look for “Lancair”, and make sure you click to search the archives, this will help you find various posts on the subject over the last year.
FWIW here’s my basic view. The Cirrus is easier to get into and to get out of. It’s interior is wider, slightly, but feels larger than the diffence of paper would suggest.
The basic avionics suite on the B configuration SR22 is better in that it is GARMIN, which is superior to UPS for reasons which I would be happy to go into detail about if you e-mail me. The OPTIONAL screen in the Lancair (an extra 14K) is superior at the present to the standard big screen in the Cirrus. However, the Cirrus big screen is still quite functional, and the promise is that with software improvements it will close the gap even more.
The Lancair 300 is sligthly faster, and more versatile in terms of load configurations due to its larger fuel tanks. Of course, it does not have a parachute, which regardless of what you may think of it, does bring a significant degree of “a feeling of safety” to non-pilot passengers as well as giving you a last-chance option. Note that neither the Cirrus nor the Lancair is an exceptionally good gliding plane, with engine out approach speeds in the 60-75kt range, which means that chute is sure nice to have if you lose the big fan up front over ify terrain.
Build quality on both machines should be equally good. However, Cirrus is several years out in front in terms of produced airplanes, and assuming you got in line now, you could figure to get your Cirrus a lot sooner than your Lancair. Likewise, there are a number of places to get the CIrrus serviced throughout the country already, and based on what I’ve read here, the factory customer-support has been excellent from the folks in Duluth.
I’m sure others will expand on these points. See also AVWEB’s series on “plastic planes” in which both are flight-tested and reviewed.
I’ve flown in SR20’s and sat in both the Lancair 300 and the Lancair 400. IMHO, the only reason to buy the Lancair would be to get the 400 model, which is turbocharged, and will be offered with oxygen. You would then likely also spend the extra $$ to get the all glass-cockpit. Assuming you can afford the extra money in return for the dazzling performance. Don’t be fooled though, you are talking 400K to do all that. If your needs are not so extravagant… well… I do believe the Cirrus has advantages, which is why you find me on this board, but both are exceptional airplanes.
