Can't get enough of these guys but a bit worried about some of the Chase prices.
I still have no clue as to why you guys are so fascinated with kubricks, but more power to ya. Jeff - you can delete this post at any time. 
They are small enough to keep without a rented space, which save some money

When the line first came out, they weren't really very pricey. Series 1 basic set of 6 cost me something like $30-35. I don't remember what the chases were going for at the time, but since they were just repaints of Fett I wasn't interested in them anyhow.
The Parco show carded figs were always spendy, but at one a year that was no big deal.
The same is true of the later series, if you picked them up as they came out it wasn't too expensive. But by series 5 those chase figures were approaching triple digits. The early boxsets were reasonable, as they were wide releases to Japan Toys R Us ($30-40 each).
But since the mail away exclusives started, and the boxsets come out commanding 200-250 each, I can't imagine playing catch-up. Now the re-releases of the series on cards are expensive, but may or may not be easy to pass on depending on your collecting habits.
As usual, it all comes down to buying what you like at prices you can live with.
