In search of ... QR code generator recommendations

Folk,

I'm looking for recommendations on QR code generators.  Yeah, I've searched, but I seek opinions from some of you who have actually used such, not new search recommendations.

In particular, although I can do the Website link thing, I'd like to also create a code that will implement the option to add information to a smartphone's contact list.  Not add it automatically, but provide a button that provides that function as an option.  Ideally, this would be a single 2D code, but I suspect 'twill be two (2) different codes - I'm not feeling particularly lucky today.

Web-based or standalone?

For web-based solutions, I have used these three:
QRStuff.com for the sheer amount of pre-set options.  Raster formats only unless you sign up.
Littleidiot.be's site allows generating to vector SVG, EPS, and PDF formats.
Kerem Erkan's site does the same, but offers hi-res TIFF files as an option, and his Android and iPhone apps come highly recommended (I've never used either, personally).

For standalone solutions, I've only used Fukuchi Kentaro's QREncode for Linux.  No gui, but it works well and can output PNG,EPS,SVG,ANSI,ANSI256,ASCII,ASCIIi,UTF8, and ANSIUTF8 formats.  A Windows version is available at the Google Code site with re-usable MSVC components available.

Never used anything for smartphone dev stuff, so not sure where to go for that.

NECRO-THREAD ARISE!

I'm looking for a QR Code Generator that can create the larger QR Codes with (blank space for) an image in the center, such as these:

The links above didn't seem to offer this feature.

An offline generator would be preferable, but I'll accept online if needed. Any tips or suggestions?

For online generation you can use QR Code Monkey
