its starting to get out of control...my addiction to star graded gold coins!

Im not sure if anyone else out there is collecting these little gems like i am but im starting to spend way way way to much money. The upside i think is that these star graded coins generally have a very low population with a large number with only one example...but will star grades stay popular? are they popular? im lucky enough to own a few of these pop 1 coins with my latest purchase a 1891cc ms61* the only star graded 1891cc...i think thats fairly special...but am i silly for paying a premium for these star graded coins?(although many i have purchased at the same price as a non star) generally i find all gold stars have prooflike surfices that must have just missed out...so sort of a half prooflike...the coins do look spectacular i think but since the "star grading" is fairly new im wondering if im wasting my money paying a premium for star graded gold...any ideas from the more knowledgeble out there? i am fresh to numismatics being an australian living in america i have only just started this year...i think my collection is fairly good for only starting this year but geez my bank balance has paid the price! o well its fun aint it! if anyone has any stars they want to rid themselves of im open to all offers! gold only

cheers
