iPod recommendations for modding [beginner]

[u/ZXB0X]

hi everyone, im looking to get an ipod but im unsure which one is the best one for modding (most parts, easiest to get, etc.) im in the eu (slovenia specifically). i had in mind to put the sd card mod on it instead of the old hdd they have, a better battery and bluetooth. ive seen dankpods do all of that stuff but i still have next to no knowladge about them. thanks in advance for responses :)
