I've got an 04 SV and I just got the Suzuki Lowers off Ebay for $400. The 08+ come with them but they are available prepainted for all the other years. I think it looks great and you don't have to take the lowers off to change the oil if you have a rear spool stand or a shallow drain pan. You can easily reach the oil filter and the drain plugs without touching the fairings. You can also get sliders for them that don't require cutting the lowers. As for the 650R, I wasn't impressed. I've gotten used to the lower ride position of my SV and the upright stance of the 650R made me feel like I was riding a cruiser. The power is very different between the two and I liked the SV much better. The suspension feel was a little better on the 650R than the SV but I've got GSXR 600 on mine and its no comparison between either of them.
