All:
Thank you much for the suggestions. I was originally thinking the Provari as I am well aware of its capabilities and durability, the price however, is a bit steep for us, even with the blems w/ the extension cap. If it were totally up to me, I would get her one, but she is aware of the price tag, and would blow a gasket (she's even not thrilled with the $110 for the Spire). I was also looking at the SVD which is up there on my choice list.
The Evic is not an option as I have heard many bad things about it, especially with the durability w/ the 510 connection. The Evic Supreme is too expensive and a 30 W device would be lost on her, and the menus alone would drive her bonkers.
The Lavatube 2.5 she is using now is a pretty descent device, just that we are both on our 3rd one (the 510 connection on it is finicky as it didn't like it when you change devices, and after a few months the threading on the tube degrades, as one of mine had to be sent back as the threading seized and I couldn't get the battery out).
Like many have suggested, I may just save up and get a Provari blem in clearance when they become available again. I do think it is overpriced a bit being it is only a VV device and not also VW, but you pay for quality in the long run.
Looks like I have some thinking to do, luckily, we are in no rush.. I'm arranging for us to have a kid-free weekend next weekend as her "main" b-day gift, with a date night on Saturday (dinner, movies, "desert" later,

).. She's not materialistic at all, so the sentimental gifts are her favorites, and she can really use a husband-wife weekend with no kids (unless you count the 3 dogs, lol). So a new device would just be icing on the cake, but it can wait a few weeks.
Thanks again everyone.
