One-man rigging aids - is the electric up/down control worth it?

My new club seems to have a culture of rig in April and derig in October! Personally I prefer to rig and derig for each flight, unless I know that there is a run of several days good weather and I'm available to fly. I have covers (Cloud-dancers) but I really don't think they offer the protection against UV that is needed for leaving it outdoors for long periods.

Anyhow, as a consequence, it's not always easy to get help to rig/de-rig so I'm thinking of getting a on-man rigging aid. It seems that I can get one from IMI for about €900 that is manually-adjustable for height and sideways alignment, or I could pay around €1500 for an electrically-adjustable version. I'm happy to pay for the more expensive one, if it's worth it. So, if any of you have any experiences/opinions, I'd be happy to hear them!

Thanks in advance.
