I'm looking to acquire a logoman of my PC player Kemba, its high on the want list. However due to the fact majority are 1 of 1s, when presented with an opportunity to acquire one it is NOT CHEAP

Just wondering what peoples thoughts are on panini logomans (game worn), are they a good store of value? Or just another card the collector will be financially hurting on?
My main worry is that they appear to be in alot of products now and have lost that overall rarity and appeal as they are in most products. I think the exquisite and ultimate ones in the 000s are truly desirable, but have trouble seeing panini in the same light.
Kemba has about 25ish true logomans in total released over his 10yr career so I so have some faith.
Any comments from people who have acquired or hold logomans would be appreciated
Thanks eveyone
