Bandai have 30MM kit which is more affordable and IMO is much more customizable.Gunpla kitbashing is fun... if you have the budget for multiple kits, and also the fucking storage space to store all the left-over parts that cumulatively piles up after every project, let alone the skill and patience to stick to a single project model for months. It's the reason most people who try to dip their toes into customizing gunpla only get as far as custom painting/weathering.
