Does the Chabrier/Kroupa form of the Initial Mass Function (IMF), as established from observations in the Milky Way, hold universally in galaxies of all types, formations epochs and metallicities?  In recent years, several independent indirect probes of the IMF in massive elliptical galaxies (spectral synthesis; stellar dynamics; gravitational lensing) have been interpreted as evidence for a substantial excess of low-mass stars, relative to the MW form.  Each of these approaches is subject to assumptions and degeneracies, and there are worrying discrepancies between results for different methods applied to the same galaxies.  In the case of lensing/dynamical methods, the challenge is accounting for the mass contribution from dark matter.  I will show how strong-lensing galaxies at low redshifts can be used to minimise the uncertainties due to dark matter and derive robust estimates for the IMF. Unfortunately very few such systems are known.  I will describe how novel IFU-based surveys can discover samples of low-redshift lenses.  I will show results from the first systems discovered in the SNELLS survey, including a critical cross-comparison between lensing, dynamical and spectral synthesis results for the SNELLS galaxies from new optical and IR spectroscopy.  Looking ahead, I consider the prospects for enlarging the low-reshift lens sample with ongoing surveys and future facilities.
