Well i was in the same situation as you, but mine was a collection of baggies.
I needed to
1. protect them better
2. make them easier to display
So after a lot of thought i decided to go with UKG.
First off the cases are nice, and tamperproof. My little lad (21 months) opened a baggie recently that i left on the side in a clamshell case :? , so i needed something that would stop any further problems.
Also baggies are very hard to display, so the nice square cases solve this problem.
Each figure costs £12 to grade, plus p+p both ways, so it by far not the cheapest option.
But im getting them done a few at a time, so the cost won't be as noticeable.
AFA grading would make them worth more instantly, but the costs involved with sending them overseas put me off. Plus who know's in a few years UKG figures could be worth a lot more than they are fetching right now, remember they are a fairly new company so people are a bit wary.
Being a new company you never know whats going to happen, but im not too worried as the baggie inside the case will still be worth something, where as if they went tits up and i'd had them removed for a U grade then i'd loose out big time.
at the moment i believe UKG are doing very well, and have moved or are moving to bigger premises, the turn around time is about 3 weeks at the moment, so they are fairly busy!.
I don't buy half as much now as i did, so im probably spending about £60-80 a month on grading.
once i have them all done i will fork out for a nice case, and then they can be displayed.
I'm not a huge fan of grading, i've been in the game long enough and had enough things go thru my hands to know what an items grade is, or if its real. BUT, i've gotta be honest and say at the moment im loving the suspence of waiting to see what grade the figures get. I'm predicting the grade each figure will get and so far i've been spot on, so its reasuring that they are inline with my grading standards. They are a not as strict as AFA, you will see that there are a lot of UKG 90's about, but imo thats not them overgrading, its UKG being honest where as AFA undergrade imo to keep 90 grade figures at a premuium!.
Anyway, thats enough babble lol.
