I got an offer for a Juniper Visa card with a incredible fixed rate interest with no annual fee. But I don't want to bother with it if they give small credit limits that aren't comparable to the big banks.

I have a Juniper account. I would not say they have low credit limits. If you are thinking about a balance transfer, it is becoming quite common to see an automatic 3% fee on the amount of the transfer. Buyer beware.

I also have a Juniper card, it's my favorite because its the lowest APR and never hopped up in the few years I had it unlike all my other credit cards.

The limit is just about where the others are for me.
