Most of my time is spent in case prep, making sure they are cleaned, trimmed to length, visual inspection that sort of stuff. Actually loading them using a neck sizer, Lee Autoprime, Lyman 55 powder measure and seating die takes me under an hour to do a box of 100 222 Rem. If the cases are already sized and primed then 20-30 minutes to dump powder and seat bullet in each for a box of 100 - that is stood at the bench with everything to hand and ready to go.
If you go down the progressive route be prepared to thoroughly check you cases before they go through the press so you know they are all good. Also be prepared to bugger it up quite a lot as you need to 'tune' each stage in the process and when one is sorted then you can identify the next and try to sort that - much time and patience needed initially then constant observation for the next few runs to make sure things are still as they should be - quicker to do the job 'properly' in the end I found.
If you are just looking for plinking ammo then go and buy Barnaul from HPS at £21/100 - their shop is between the clays and William Evans, a large white building with black detailing. Phone them first to make sure they're open as the TR season is winding down - number is on their website.
I CANNOT reload my 222 Rem for that as cheapest bullets are about £14/100, primers £4/100 and even using N120 powder works out about £8/100 so total cost is £26/100 plus all my time and effort.
As for Lee quality... all I can say is look very carefully at each item you buy some is great, like the Auto Prime and the case trimmers and length gauges, other stuff is total carp, presses made from white metal will not stand much use in my experience.
