Thanks for the input! I figured these prices were great.
I do have another follow-up question as I'm still new to this Brio thing.
I managed to get a new Brio Deluxe Railway set (33052) for a really good deal ($150) on eBay but I'm curious what I should get (additional trains, track expansion?) that would round out my collection. I'm happy to spend another $200 especially since the seller informed me that they can bundle the sets to save on shipping costs. Also I'm not fixed that everything has to be Brio as well and don't mind mixing the non-official tracks if it does save some money there.
Hopefully, there are some master Brio builders here to know how I can efficiently expand on this set. I also plan on getting some of those Duplo + Brio adapters as well since my soon-to-be 3-year old daughter is into building things and did ask for a train set. :D
