I know you had your heart set on a Flip up, but may I suggest that you look at the whole line. If the flip up is needed for cleaning, then look at a good hoist like a Pro lift

This was my concern when I purchased and was looking into costs, when I decided that "if there is more parts then we have more things to go wrong"
But if space is an issue and you are looking at where to put it then invest in a shed, or even In my area people have been looking at the used shipping containers.
Plus with the winter season coming, and I have done my last cut with snow on the way. This gives you the upper hand with the dealer, do not go back in to see the dealer ~ play the waiting game and you know he needs cash and will call you if He knows you. This is a way of getting a better price but have a back up plan that allows you to walk away.
Good luck!
