Not really, I've had several along the way, mostly on the lower end: Crown, Parker, etc. Right now, I'm using a plastic Pilot VPen (disposable, horrors!), which works fine.
Your post of your newest did whet my appetite for one, however.

Very interesting! I wonder if you stepped up to a Lamy Safari or equivalent maybe you would find you like it enough to hold onto it longer?
I've honestly not tried the disposable pens.
