What size EZ-cube is reccomended for Mini's?

I have a metre square one that fits both my mini's a bambi elf and several tinies in it quite comfortably, sadly tho, it is HUGE and takes up half a room when it's up...hence my barely ever using it...

 

I can't think of the exact measurements off the top of my head but I think mine's around 50cm square and that fits an msd but it's too cramped (bought it ages before I had a doll >.<)

Tbh if you don't have a pair of lights to go with it a light tent is pretty much pointless, a set of lights and the tent cost me £70 and you'll be wanting a bigger tent so that could push it over £100 (roughly $190). In all honesty a piece of fabric for a back drop/infinity curve and a window/lamp would do the same just just as effectively for doll photography. (if not better. Natural light is )

Camera wise what ever you get, bear in mind you get what you pay for. I'm guessing you'll be after a compact?
If that's the case anything with 5mpx+ should suffice if you're only going to be using the photos for the internet/personal use, the only time you really need to go 10+ is if it's for print.
I can't stress this enough... try before you buy if possible, a lot of lower end compacts have very noticible, very annoying shutter lag and don't forget to factor in the cost of the memory card too... you can get 1gb cards pretty cheap these days but it's still a cost to bear in mind.

cameras with the flower symbol setting are a godsend (macro I think it's called)

 

Yeah it's macro. It can be kind of hit and miss on point and shoot cameras though sometimes

 

I have a Canon s3 IS, I think there are newer models but it costs me around $300 USD plus postage and peripherals. I really love the zoom lens on it, and the super macro is an awesome little trick that allows you to take pictures of things that are almost or even touching the camera lens.

I made a cardboard box light tent and its' probably two feet tall by two and a half wide and it's not big enough. I can put her bed in it and that's about it, since you need room to hide the walls of the box. I just can't make my family sacrifice the amount of room I would need for it so I'm going to try to rearrange the furniture in my bedroom so i can utilize my window for natural light better.

 

To be honest if you want white backgrounds a table lamp isn't going to cut it as it'll give a very orange cast to your photos so it'll mean a lot of tweaking in photoshop even if you have a decent camera.
Specialist lamps/flashes use 'daylight' bulbs with a colour temperature of 5500k (http://en.wikipedia.org/wiki/Light_temperature)

Then move them... clear a space, set up a background (i.e. a piece of cloth pinned to a wall or draped from somewhere in a well lit room) I do most of my studio style doll photography in my hallway with a backgound cloth proped up by the washing basket, I've only ever used my light tent once for doll stuff and that was just a pain in the arse.

If you want to use a window bluetac a sheet of paper to it, it'll create almost the exact same effect as a light tent if you're doing bust shots.
