Handle upgrade options (2008 Lenni)

[SueD]

I purchased a used 2008 Lenni last summer.  This machine has the stationary vertical handles in front.  I asked APQS a few months ago if it was possible to upgrade to the adjustable ergo handles.  I was quoted $450 for them and installation will require me to drill holes for mounting.  Has anyone else done this and if so, are you happy with them?

I was thinking that would be a lot of money and may someday I would want upgrade my machine so why spend the money now.  But the more I think about it, it seems I should just stick with this machine for the foreseeable future.  The new machines are a significant investment and this is just a hobby for me.  Are there any other upgrades I should consider?

Thanks,

Sue
