Yep, sure do like other Robots/Mecha but my spending tends to get focussed on one particular franchise.

I quite like the Giant type robots such as Giant Robo, Shin Getter, Tengen Toppa Gurren Lagann (Still yet to watch this series though), Voltron & the 1st series Power Ranger's Megazords.
There is a multitude of other things I'd love to get but I just don't have the wallet or space for them at the moment.

I'd really like to take a further walk down the Soul of Chogokin line as I was really impressed with my Tekkaman Blade with Pegas and it's to my understanding that it's probably one of the lower-end figures in that line.

If I had money and space to burn, I'd definitely consider 3A's World War Robots - Big, Hefty, 'High-End' collectibles with a very 'Steam-Punk' WWI-II vibe.
(This is probably something that wont eventuate any time soon though )

Also, Mazinger Z!
