Ad network with banner

Which ad network would you suggest for banners if I don’t have a chance to use admob?

I am using leadbolt, but eCPM, CR is very low. CTR is good, at least around 0.5-2%, but eCPM is always around 0.03-0.08$.
30-35% impressions are from USA, mostly around 30-40% from EU. But even for clicks and actions from US I get 2-5 cents max.

People say that Airpush has less fill rate. What about Startapp banner? I just don’t want to use two ad networks for just banner. I changed interstitial from leadbolt to appnext, but they don’t have banner ad.

It even seems that I better use Tapjoy than leadbolt, with tapjoy for actions for sure u get 8-25 sents (it is possible to calculate in tapjoy)

Thanks in advance

P.S: Leadbolt stats:
Impressions: 13,360 (even 5% are interstitial)
Clicks 103
eCPM: 0.06$
CTR: 0.77%
Revenue: 0.78$

I prefer startapp or airpush;) of course it depends on your users country. There is also applovin (goos for some regions)
