The Bushy looks good and gets a lot of nice reviews. Just ordered today an Ebay item Vortex Sparc 2..Seller accepts offers so you can get the item at a really low price plus he/she is a certified dealer.
Just got my Visa card a few days ago so now I am devirginizing it, lol! The 1st one was compromised, someone opened the envelope containing my card so I requested for a new one. Sorry, off topic, lol again!
Although the Vortex is more expensive, their no-questions-asked lifetime warranty won me over. Also. it has a 2 moa dot, a bit smaller than the Bushy's.
I will post pics of it once I get it sometime next week. Mounted of course on my URX
PS: You may want to check this out too...It has ( I think ) better features than the Sparc 2 but their warranty is limited to 5 years or so if I understand it correctly.
