I agree with most here, I'd rather wait and get what I really want and can use. I only got an Evelyne after buying a K and a B, simply because I loved the colour (Bleu Izmir) and wanted a cross-body bag at that time.
As so many posters have inferred -
You have to decide what it is that you want.
Is it that you just want a piece of Hermes?
Is it that you just want to buy something in a Hermes shop?
To buy a bag and enjoy it, you have got to know how it will fit in to your lifestyle.
Consider the kinds of bag you use; is there something similar in Hermes?
That could help you with your answer - even if you have to wait for it.
If it is more the Hermes experience - buy a silk scarf; buy some silk scarves and feel extravagant and enjoy it.
Whatever, most posters on here will agree that you have started down the slippery slope - enjoy the ride.
